I doubt this is going to be her problem. If the car worked fine 2 days ago it would be impossible for the fuel injectors to get clogged if the car was not even on. Make sure you have your MAS hooked back up to the air intake. I know i disconnected mine when i was installing mine and forgot to plug it back in and started the car and it died after about 10 seconds. If the car is ideling that low then the car has to be leaking air somewhere. Did you make sure all the hoses in the very back of the plenum were hooked up properly? You should have 2 in the rear of the plenum and also the 1 on the left. Double check on all the bolts again and make sure they are tight (dont just look at them and assume they are tight...go through and physicly make sure they are tight). Reset the ECU before turning on the car and you should be set. If it still doesnt work then i have no idea what it could be.

EDIT: when you had the upper plenum off did anything fall down any one of the 6 holes that are on the lower plenum???

DOUBLE EDIT: Didnt see that this thread was started about 2 weeks ago. Sorry

 

the car was on... he had it running at very low rpms and then added gas. fresh gas could have stirred up the gunk off the bottom and sent it through. That is why I suggested that
